Luckily I could survive this purchasing mistake due to the help of the little FIIO E6 which I bought after some research for its EQ options and the possibility of using a FiiO L3 Line Out Dock (LOD) Cable For iPod and iPhone so no battery will be drained from the power hungry V-Modas. I found that the third setting, the blue colored led option boosted the mids so nicely that made a huge improvement in SQ.

It turns out that the little FIIO actually flattens the M80 soundstage and make it sound a little artificial and dull. So for a better set of headphones this little guy can do more harm than good although it can work very well with some sets that lack bass or have a noticeable bump in the lower mids that makes the sound veiled or muddy. For the Crossfade LP it is a miracle. For the M80 it is not a compliment neither a necessity.
